A monolithic MQW InP-InGaAsP-Based optical comb generator [PDF]

, 2007
We report the first demonstration of a monolithic optical-frequency comb generator. The device is based on multi-section quaternary/quaternary eight-quantum-well InP-InGaAsP material in a frequency-modulated (FM) laser design. The modulation is generated

Phase Noise Reduction of an Optical Frequency Comb Using a Feed-Forward Heterodyne Detection Scheme

IEEE Photonics Journal, 2016
A novel feed-forward phase noise reduction scheme is introduced to reduce the phase noise of an optical frequency comb. The phase noise of a single comb line is measured using a heterodyne technique, and the inverse of this signal is then applied to the ...

Integrated dual optical frequency comb source [PDF]

, 2020
A monolithically integrated dual-channel optical frequency comb source is demonstrated in this paper. Three lasers are integrated on a single chip using a regrowth-free fabrication process in a master-slave-slave configuration.

Mutual optical injection locking dynamics between a terahertz single-mode laser and a frequency comb laser [PDF]

APL Photonics
Frequency combs are powerful tools for precision metrology, spectroscopy, and communications. In the terahertz (THz) domain, the quantum cascade laser (QCL) offers an on-chip platform for self-started comb generation via four-wave mixing.

Frequency-comb-induced radiation pressure force in dense atomic clouds

, 2021
We investigate the frequency comb induced radiation pressure force acting on a cloud of cold $^{87}$Rb atoms. Reduction and spectral broadening of the frequency comb force are observed as the cloud's optical thickness is increased.
